What the Data Says About MSP to XWA

The Minneapolis to Williston corridor (MSP → XWA) covers roughly 553 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,412 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 87.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,599 flights were recorded on this pairing — 13 cancelled (0.8%) and 10 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,412 total flights analyzed, the 83.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 87.1-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Sep 2024 posted the best performance on this corridor at 95% on-time, while Dec 2025 came in at 48% on-time — a 47-point gap between best and worst recent month. For travelers evaluating the MSP to XWA route, the combination of a 83.3% on-time rate, 87.1-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
